ing fire-place stovepinwhich are combined the following elements, namely: 4a cylinderor body 1 "projecting outward from the mantelor frame, i

a fuel magazine orfeeder `within the ,said cylinder, and an .opening through whichthe said g magazine can be fcdfrom above. A The object" of this part of my invention is to increase the capacity of the fuel-magazine5 secondly, of a base-burningire-place stove or heatenin which the magazine or feeder is extended to the feedopening of the'outercasing, so that there may beV no open spaceacross which to project the fuelon teedingthe magazine; thirdly, iny the combination, with a tire-place stove or heater, of a feeder or magazine projecting above the tol) of theheater, sol asto increase the capacn ity of the'said magazine.. .i

Figure l -is a front view of my improved i fire-place heater, Fig. 2, a-verticalseetion of thesame; Figr, a sectional plan; Fig. 4, a planview` with part of theirnantel removed;

Fig.` 5, a view ofthe fsliceror plate'to be introduced into there-pot under the ffeeder, for the purpose of holding up the `coal which isunconsumed when theclinkers,' ashes, Ste., inthe lower part of the `lire-place have to be removed. Fig. 6 is a plan view of the grate, andFig. 7 an edgeview of the grate.

My improved Vfire-place heater is made in two parts, the part 'd beingv a stationary concave, fitted to and set in the lire-place b below the mantel c, and having a Front plate or frame, d, similar to that ofan ordinary grate, and adapted to theshape ot' the movable' part of the heater or stove, the latter being arranged to" slide in and out of the stationary concave a upon guides al attached to the bottom plate a? of the stationary concave. Whenthe heater is not required to be used, the movable part may be withdrawn from theiire-place, and a summer-piece so fitted to the latter as to close the opening cave.`

The .object of the guides is to, .soldirect [the movable part when it ispushed` into the stal tionary'partthat the short funnel or ontletfot"L for the products otl combustion` will pas'sfintothe short, slightly-conical collar a?, which pro-v jects inward froin the concave a, near the-betr,

: tom plate. A good joint-isthus produQBdv and thel leakage of products ocombustion intothe airspace between the concave and the movable part of the heatedsprevented.

It will'fbe'ohservcd that theback of,.thecon cave a, isset at a little distance from ,the4 back ofthe chimney, so that the heat alidiprduets of combustion from the liuc-passage a4, which pass through the concave, as heforedescribed,

mayI pass up the chimney' behindthe concave, Aand thus'malze the concavea heating-plate 0for `the air, 'which passesin. contact with its opposite side. In the base of` the .movable part ofthe heater is an Vair-chamber, f, *which` may receive air from thereon;v byholesj1 in theilaringbaselplatef?, or air may bebrought into the chamber from below. vthrough holes in the hearthl or bottomplate..5'v Somecf the airfrom this chamber f passes throll'gh holes g vof the flaring base-plate, into Vthe space be; tween the concave .a andthe indrical jacket h'of the movable part of the Ehe up into the distributing-chamb 4 f a hot-air Ipipe, il, p conduct heated ,air through the chimney (showin `rolfren' oifin the drawings) to the room or rooms` above in the usual Way. chamber f also passes up through a set ot' vertical air-heating tubes, j, at the rear of and fronilwhicli -iug secured on the two .circular plates 7'1 jz, which ferm the top of the receivingchamber, and the bottom of the distributing-chamber, and which, together with the cylindrical jacket h, form the inclosure in which are situated the inclosed ash-pit k, the fire-pot m, andthe lower portonof the feeder or magazine a.

In order to protect the lower part of' the feeder or magazine from the lire, and also to obtain a circulation of air downward from the top ofthe stove to the fire-pot to assist in burning the gases, 1', in the present instance construct the magazine with double walls, nl.

in frontfofthe Stationsweg@ ...malaises The air from thereceivingim?,'liavingsntlcient room between vthem for a .v bodyof air, andcommunicating with the outside air by holes n at the top of the feeder, and with the fire-pot by holes at the bottom of the feeder, so that air shall enter at the top of. the air-space, between the Walls of the inagazine, and pass down to the tire-pot for the purpose of keeping the lower part of the feeder comparatively cool, protecting the coal in the feeder from combustion, and supplying air to burn the gases from the burning coal in the fire-pot. y

A more minute description of my improved heater than that given above will be unnecessary, as several of the parts described and illustrated in the drawings, form the subjects of other patents, and my present improvements relate especially to the top-feeding arrangement of a fire-place stove or heater. I will now refermore particularly to these improvements.

In constructing my 4im proved heater I have so combined three elements or features as to produce an important result. rIhese features are as follows: first, a cylinder or body of the heater projecting outward from the frame l or mantel; second, a feeder or fuel-magazinev It has been the practice torso construct baseburning fire-place stoves or heaters that the fuel had to be` introduced into the feeder or `magazine through a doorway in front; hence the magazinel was of a very limited capacity. By so arranging thefeed-hole, however, that the fuel can be introduced into the magazine from above, the capacity of the magazine is burning lire-place stove.

The second part of my invention consists in extending the feeder or magazine to the feed-hole of fire-place stoves. This not only increases the-capacity of the magazine to some extent, but an uninterrupted passage or guide is afforded for the introduction of fuel into the magazine through the opening in the outer casing.

The capacity of the magazine is still further increased, in the present instance, by carrying the feeder up above the top'of the heater, by placing thereon a movable section, o, furnished with a cover, o1, which has to be lifted oif when coal has to be introduced into the magazine.

At and around the base of this removable section 0 is a flange, o2, perforated with holes to match the holes in the feeder or magazine, so that by turning the removable section the air-passage through the walls of the feeder may be closed wholly or partially, as desired.

In case the upper section o of the feeder should be made in one piece with the feeder, a registering-plate, ,perforated with similar holes, may be used in place of the flange.y

I claiml. A base-burning lire-place stove, in which are combined the following elements, nalnely: a cylinder or body projecting outward from the mantel or frame, a fuel-magazine or feeder Within the cylinder, and an opening through which the said magazine can be fed from above.

2. A fire-place stove or heater, in which the magazine is extended to the feed-opening of the outer casing.

3. In combination with a fire-place heater, a feeder or magazine projecting above the top of the heater, substantially as described..
